Wiring the D-Shell Connectors
The following figures show the wiring information for the
D-Shell connectors.
1790-16BVOX Input Module Wiring Diagram for D-Shell Connector
• For inputs 0-7: Sinking inputs - wire Com 1 to Field Power (+) 24V dc, wire
Com 0 to Field Power (-) GND
Sourcing inputs - wire Com 1 to Field Power (-) GND, wire Com 0 to Field
Power (+) 24V dc
• For inputs 8-15: Sinking inputs - wire Com 3 to Field Power (+) 24V dc, wire
Com 2 to Field Power (-) GND
Sourcing inputs - wire Com 3 to Field Power (-) GND, wire Com 2 to Field
Power (+) 24V dc
Note: All Com 1 and Com 3 are internally connected - Com 1 is used for inputs
0-7, Com 3 is used for inputs 8-15.
